Langbeinite is a popular fertilizer, especially where several nutrients are needed to provide adequate plant nutrition. It has an advantage of having K, Mg, and S all contained within a single particle, which helps provide a uniform distribution of nutrients when it is spread in the field.
Its neutral pH does not alter soil acidity and its maximum chlorine content is less than 3.0%, minimizing potential for fertilizer "burn".
Langbeinite is totally water soluble, but is slower to dissolve than some other common K fertilizers because the particles are denser than other K sources. Therefore, it is not suitable for dissolving and application through irrigation systems unless finely ground.
